IN Brief:
- Bühler has introduced Edition 26 versions of its Finer S five-roll refiner and ELK S single-shaft conche.
- The systems add Playone automation, improved hygienic design, remote access, and more precise control over refining and conching.
- The launch strengthens chocolate manufacturers’ ability to manage quality, yield, energy use, and raw-material pressure.
Bühler has introduced Edition 26 versions of two of its core chocolate mass processing systems, updating the Finer S five-roll refiner and ELK S single-shaft conche with automation, hygienic design improvements, and energy-efficiency features.
The systems target two stages that define much of the final quality and economics of chocolate production. Refining controls particle size and mouthfeel, while conching influences flavour development, moisture removal, volatile reduction, flow behaviour, and fat release. In factories managing cocoa volatility, recipe changes, and energy costs, those process steps carry direct weight across yield, waste, quality, and line efficiency.
Within the Finer S Edition 26, sensor-based process monitoring allows roll speed, pressure, and temperature to be adjusted without constant manual intervention. The system is designed to keep fineness consistent while reducing dependence on operator experience, which remains a significant issue in plants where skills shortages and shift-to-shift variation can disrupt process stability.
Bühler has also integrated IE5 motors into the refiner, with energy consumption reductions of up to 3%. Although that saving is incremental, refining equipment often runs across long production cycles, making small efficiency gains commercially relevant over sustained output. Easier access, cleaner operation, and reduced downtime have also been built into the design.
The ELK S Edition 26 single-shaft conche has been redesigned around operation, accessibility, hygienic layout, and energy performance while retaining the company’s established conching tool geometry. The system uses intense shearing to support flavour development, mouthfeel, and fat release, with Bühler citing energy consumption reductions of up to 30% and fat savings of up to 2% through improved shearing and process control.
Both systems include Bühler’s Playone automation platform as standard. The web-based system enables remote monitoring and control from authorised factory devices, including tablets, desktops, and smartphones. That shifts operator time away from repeated manual adjustment and toward quality supervision, exception handling, and production oversight.
The Edition 26 systems extend the equipment programme outlined in Bühler’s interpack 2026 launch plans, which covered cocoa roasting, chocolate compounds, spreads, coatings, bakery, wafer, extrusion, and energy-focused production systems. The latest refining and conching updates sharpen that portfolio around two of the most influential stages in chocolate mass production.
Chocolate plants are being pushed into a tighter operating envelope. Cocoa prices remain volatile, manufacturers are testing reformulated recipes, and finished products still have to deliver the same texture, flavour release, gloss, and shelf-life performance. Refining and conching now sit at the centre of cost control as well as product quality.
Recipe pressure adds another layer of difficulty. Alternative fats, cocoa-reduced systems, sugar changes, dairy ingredient adjustments, and premium inclusions can all alter viscosity, flavour release, and downstream handling. Processing equipment that can hold parameters more consistently gives development teams a stronger route from trials into full production.
Automation is becoming equally important as manufacturers move away from isolated machine performance and toward connected process control. More data from refining and conching can help technical teams link upstream conditions to final product quality, investigate deviations faster, and reduce losses caused by inconsistent fineness, unstable flow, or recipe drift.
Energy performance will also influence investment decisions. Chocolate production draws heavily on heating, cooling, mixing, refining, conching, moulding, and packaging systems, all of which compete for efficiency gains. A conche that can reduce energy use while preserving flavour and mouthfeel addresses operating cost rather than simply adding a sustainability claim.
Customer trials will test the systems against installed equipment, recipe complexity, cleaning requirements, throughput, and return on investment. For confectionery plants, the next generation of chocolate machinery has to do more than produce a fine particle size or run a familiar conching profile. It has to help factories absorb volatility, make reformulation less risky, reduce intervention, support traceability, and protect line economics while keeping finished-product quality intact.
